BOILER CLEANER.

Application filed April'28, 1919. Serial No. 293,155.

The invention relates to boiler cleaners and has particular ieierence to a novel construction of bearing for supporting the blower tube.

It is highly desirable in the installation of blowers tolocate the blowertubes where they will be cooled by contact with or proximity to an extended portion of the boiler surface. Thus where a boiler is 'i'ornied with a waterleg or aheader to which the'tubes" are at tached,'the placing of the blower tube in contact with said legor tageous. a

be present construction is designed to hold the blower tube in such alooation pr vent displacement thereof and at the same time to avoid the interposition of anything which will space the blower tube from the. cooling surface. The invention therefore consists essentially in a member which is clamped to one of the boiler tubes and is provided with a hooked or angular portion for engaging the blower tube to hold the same against the waterleg or header and adjacent to the supporting boiler tube.

In the drawings:

Figures 1 and 1 are respectively end and side elevations of one construction of bearing or hanger;

Figures 2, 2, 3, 3 4 and 4* show modified constructions.

As indicated in dotted lines in Figures 1 and 1 A is a header or waterleg of a boiler and B one of the water tubes connected with said leg or header. C is a hearing or hanger which has a segmental portion C for fitting about the tube B and a portion C extending in a plane parallel to the tube and bent laterally in-tlie same plane to form the hooked portion C The member C may be clamped to the tube- B by suitable means, such as the U-bolt D, and when in position will be in such relation to the header A-and tube B as to provide a space for receiving the blower tube E. This tube is arranged in a. plane at right angles to the axis of the tube B and lies adjacent, to the header A, being retained therea tainst by the portion C and being held Irom displacement in a transverse plane by the hooked portion C Thus there is nothing interposed between the blower tube and the cooling surface A, while at the same time displacement of the tube in any direction is prevented.

head G for engaging a slotted flange H cure said members in clamping posi larto that shown in Figures 1 and l header is a'dvan-,

QT and K which are slid into engagement With the construction shown in Figures 2 and 2", in place of a U-bolt for clan-ping by a co-operat-ing member F having a T- while a single clamping bolt I on the op-- posite side of'the water tube serves tose- The construction of the hooked bearing pr 7 tion for retaining the blower tube 1' sumlVith the construction shown in Figures 3 and 3. the hooked bearing for retaining the blower tube is the same but the clamping is effected by co-operating toothed segments with each other longitudinally of the boiler tube and are clamped by a single bolt L.

"With the various constructions described, the securing of the blower tube in position is easily accomplished, as the bearing mem ber may be rigidly engaged and secured to the boiler tubes. At the same time the blower tube is protected from overheating by its proximity to or contact with the surface of the header or waterleg.

Where the blower tube is vformed with projecting nozzles there is danger of interference between these nozzles and the portion of the hanger embracing the boiler tube, since the nozzles are usuall so set relative to the side of the boiler to e that the discharged steam jet will just clear the side of the boiler tube. To avoid this I have de vised the construction shown in Figs. 4 and 4, in which the hook N is formed with a segmental bearing portion 0 for holding the blower tube away from the plane of the inner side of the hanger. This provides clearance for the oscillation of the nozzle P without interference with the segment engaging the water tube.

What I claim as my invention is:

1. In a boiler cleaner, the combination with an extended portion of the boiler surface and a boiler tube extended transversely thereto, of a blower tube lying adjacent said extended surface, and a member clamped to said boiler tube for retaining said blower tube in contact with said extended portion of the boiler surface.

2. In a boiler cleaner, the combination with a. portion of the boiler surface extended in a. plane, and a boiler tubeextending transversely to said plane, of a blower tube arranged parallel with said extended surface and adjacent to saidboiler tube, and a retaining member for said blower tube clamped to said boiler tube having a portion in a plane parallel to said extended surface and a portion in a plane parallel to said boiler tube, the latter portion supporting the blower tube in contact longitudinally of its length with the said extended portion of the boiler surface for exerting a cooling effect on the blower tube.

3. In a boiler cleaner, the combination with a portion of the boiler surface extending in a plane and a boiler tube extending transversely to said plane, of a blower tube arranged parallel to said extended surface and in the angle formed by the same and said boiler tube, and a member clamped to said boiler tube and provided with a portion spaced from said extended surface for supporting the blower tube in contact with the extended surface.

4. In a boiler cleaner, the combination with a water leg, or header and a boiler tube extending transversely therefrom, of a blower tube lying in contact with said header and in the angle between the same and said tube, and means for retaining said blower tube in said position comprising a member having a segmental portion embracing said boiler tube and a portion extending therefrom spaced from said header and provided with an int-urned hook extending toward said header for receiving the blower tube and clamping means for securing said seg mental portion to said tube.

5. In a boiler cleaner, the combination with a. water leg, or header and a boiler tube extending transversely therefrom, of a blower tube lying in contact with said header and in the angle between the same and said tube whereby the blower tube is cooled by the header, said blower tube being provided with projecting nozzles, and hanger means for retaining said blower tube in position comprising a member having a segmental portion embracing said boiler tube and a hooked portion extending inward to said header spaced from said tube to embrace the blower tube, saidhooked portion having a bearing offset from the main body of said hanger means for receiving the blower tube and holding the same out of the plane of the inner face of said hanger whereby the projecting nozzles will clear the segment engaging the boiler tube.

In testimony whereof I affix my slgnature.
